I have said it many times in this forum, do not spend money on the clear vinyl mask on motorhomes or cars/trucks, it will cost you more over time, it will turn yellow/brown from to much sun or mildew from to much moisture, deal with rock chips with touch up paint..
Removing the mask will destroy the paint, I know this from others experience here in Vegas, I know a guy that had this put on a expensive sports car when it 1st came out by 3-M, he parked it outside at work in sun everyday, yes it turned yellow and he paid a ton to have it removed and roof of car repainted to match, its not worth the cost, trust me...
